A RACIST thug who smashed a Sikh builder over the head with a lump hammer outside Coventry's University Hospital and left him unconscious has been jailed.

Martin Baker, 18, chased his terrified victim Ranbir Hayer with the hammer before hitting him on the arm and the back of the head.

Just minutes earlier he had launched an unprovoked attack on an Asian medical student outside the hospital.

He was sent down for 43 months for the attacks, but is only expected to serve half that sentence.

His older brother Jason Baker, who was also involved in the attacks, escaped jail but was handed a suspended sentence at Coventry Crown Court yesterday.

The court heard how the brothers binged on home-brewed wine before spotting a group of medical students as they walked through the grounds of University Hospital, in Walsgrave, shortly after 5pm on March 30.

Martin grabbed one of the foreign students, called him “monkey face” and pushed him back against the railings.

Jason, aged 20, then joined in, punching their victim and a female student who tried to intervene.

Judge Marten Coates said: “This was a squalid attack against students who had done a hard day’s work and who were going home through the grounds of the hospital when they came up against two loutish drunks.”

The brothers then walked off down Hall Lane in Walsgrave where they saw two Sikh builders finishing a wall in a front garden.

Jason racially abused one of the builders. Moments later he returned followed by his younger brother, who picked up a three pound lump hammer.

Martin used it to attack one of the builders – Ranbir Hayer – knocking him unconcious and fracturing his skull.

Jason was identified using CCTV footage from University Hospital and Martin handed himself in several days later.

The court heard how police found racist video clips on Martin’s phone.

Sentencing, the judge told Martin there was “no mitigation” for his attack.
